Ubuntu Installation :: Dual Boot With Debian - Write /dev/sda1 To The Bootloader Rather Than /dev/hda1 Using Grub-mkconfig?

Aug 19, 2010

I installed Debian on my PC and then installed Ubuntu. This worked fine and I could dual boot between the two. The PATA disk was /dev/hda on debian and (I think) /dev/sda on Ubuntu. I copied the entire disk to a sata disk using dd from knoppix and put the PATA one to one side. Now the Ubuntu comes up fine but when I boot debian, it complains about references to /dev/hda1, which is present in grub - root=/dev/hda1. Debian now expects sda references rather than hda references. How do I persuade Ubuntu to write /dev/sda1 to the bootloader rather than /dev/hda1 using grub-mkconfig?

Debian Installation :: Grub Bootloader Only Show Kali Linux To Choose From - Screen Not Allowing To Boot From CD

Nov 29, 2014

Basically I had windows 8.1 running on my fujitsu lifebook A532 laptop and wanted to dual boot kali linux alongside it, however upon installing the linux it deleted EVERYTHING! on my laptop, the grub bootloader only showed kali linux to choose from...

I then decided kali linux is too complicated for me and decided to delete everything and reinstall windows 8 again however I was surprised that my bios screen looks diffrent also I can not edit the boot sequence.

If I press f2 or f12 it takes me to a screen with a tab named Boot menu and its written on it debian and every time I press enter on it it takes me back to this same screen...

I can not boot from cd or usb!

Ubuntu Installation :: Unable To Boot On Dual-boot XP After Recovering Windows Bootloader?

Jul 18, 2010

I have Ubuntu 10.04 LTS and Windows XP installed on my laptop. Usually when booting, I get the GRUB 2 menu and I can boot into either Ubuntu or XP.I was playing around with EasyBCD, then after trying to remove it I was unable to boot into Windows, I used a Windows 2000 CD recovery console to fix the MBR (using: fixboot and fixmbr).Now Windows starts up when I power on, but I don't get the grub menu anymore with an Ubuntu option. If I boot from the Ubuntu Live CD and try to mount my Ubuntu partition (/dev/sda5) I get this error:

mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

Debian Installation :: Cannot Write Grub To Boot Location - Fatal Error

Jun 10, 2011

I have been following this tutorial [URL]. When I get to the end of the installation and try to install GRUB to the /boot partition I have set up it throws a fatal error at me. No explanation other than it can't write to the specified location. I double checked all the partition settings which were the same as the tutorial then skipped the GRUB installation and finished. The only thing I can think of that might be wrong is that the 250MB partition size specified for /boot in the tutorial is too small.

Fedora Installation :: Using The Windows 7 Bootloader To Dual Boot

Jan 19, 2011

I am getting a new computer with Windows 7 installed. It will contain a second hard disk on which I will install Fedora Linux. I plan to put grub in the /boot partition of that disk,so I won't be able to boot Linux directly to start. I plan to use the Windows 7 bootloader to dual boot, and I understand in principle how this is done. I set up a previous computer which was running Vista this way, using the program Easy BCD which simplified setting up the Vista bootloader. But the Easy BCD website doesn't address the question of what to do with Windows 7.

Ubuntu Installation :: GRUB2 Bootloader Crashes With Win7 And 10.04 Dual Boot?

May 7, 2010

I have a Dell Studio 14 laptop with Windows 7 64bit preinstalled. The processor is core i5 and the machine has 4GB RAM. I freed 25GB of memory from my Hard disk and tried to install Ubuntu 10.04 (AMD). Everything went fine. I restarted and Logged into Ubuntu. It worked like a charm. Then I restarted to Windows7. This also worked well as expected.

But, when I rebooted again, I got a black screen saying that �No modules found. Press any key to restart�
When I press a key, it says �No operating system found�, probably after checking through a network (it printed lines starting with PXE).

I tried exactly in the same way with Ubuntu 8.04 in my machine, and this worked without any problem. The Bootloader was not corrupted after restarting from Windows. I noticed the problem with Ubuntu 9.10 and 10.04. I feel like a problem regarding the bootloader version. AFAIK, 9.10 and 10.04 is using GRUB2 when 8.04 use the old version of GRUB. Will I have to switch to the legacy GRUB? (I would love to keep using GRUB2). If yes, I would like to know How.

Debian Installation :: UEFI GRUB Broken - Dual Boot 7.7 And Win 8.1

Dec 23, 2014

My Toshiba Satellite C870-198 has Debian 7.7 installed in UEFI mode alongside Windows 8.1. The GRUB menu no longer displays, but the machine boots straight into Windows.

I can boot into Debian or Windows from rEFInd installed on a USB stick. The rEFInd menu has the following entries:

The Debian entry actually launches the GRUB menu which was installed with Debian.

Code: Select allBoot Microsoft EFI boot (Boot Repair backup) from Basic data partition.
Boot supposed Microsoft EFI boot (probably GRUB) from Basic data partition.
Boot EFIubuntugrubx64.efi from Basic data partition.
Boot EFIdebiangrubx64.efi from Basic data partition.
Boot bootootx64.efi from Basic data partition.
Boot vmlinuz-3.2.0-4-amd64 from boot.

In an attempt to fix GRUB I executed the commands in the 'Reinstalling grub-efi on your hard drive' section of: [URL] ....

Code: Select allmount /dev/sda1 /boot/efi
... surprisingly returned:
Code: Select all$LogFile version 2.0 is not supported.  (This driver supports version 1.1 only.)
$LogFile version 2.0 is not supported.  (This driver supports version 1.1 only.)
Did not find any restart pages in $LogFile and it was not empty.
The file system wasn't safely closed on Windows. Fixing.
Code: Select all[ -d /sys/firmware/efi ] && echo "EFI boot on HDD" || echo "Legacy boot on HDD"

... returned "EFI boot on HDD".

[Code] ....

... Where is Debian?

FULL HISTORY ....
=============================

The laptop came with Windows 8 preinstalled. I switched off Secure Boot and installed Ubuntu for UEFI dual boot. I recall having to use Boot Repair to get the GRUB boot manager working properly for both systems.

Recently I decided to replace Ubuntu with Debian 7.7 and first cloned the entire hard drive to a USB drive (The Clone Drive). This drive successfully boots into Ubuntu in UEFI mode.

Following this I took the opportunity to update Windows to 8.1, which broke GRUB as expected, so that the machine would only boot straight into Windows.

I installed Debian from a live USB stick in the mistaken belief that it would be bootable in UEFI mode. It did boot OK in legacy mode.

I then burned the full Debian 'DVD' image to a USB stick, booted it in UEFI mode and reinstalled Debian. In UEFI mode GRUB allowed me to boot into both Debian and Windows.

At this point I tested The Clone Drive. It was still able to boot into Ubuntu as previously, but after powering down, unplugging The Clone Drive and rebooting, the GRUB menu failed to appear and the machine booted straight into Windows. This is its current state.

Debian Installation :: Dual-boot Grub Rescue Says No Such Device

Feb 13, 2015

I'm inexperienced in Debian. I have a dual-boot machine (64-bit, Debian 7.3, Windows 7, legacy boot) and encouter a problem at boot ever since I completed the installation of Debian 7.3 alongside the exising Windows 7. This machine has six hard drives: two are intended for ntfs storage of general data (raided together by RAID1); two more are intended for ext4 storage of general data (also raided together by RAID1); the fifth contains the Windows OS files and the sixth contains the Debian OS files. The problem is that I arrive to the grub_rescue each time at boot, seeing the message:

GRUB loading.
Welcome to GRUB!

error: no such device: e081517b-3399-4067-9294-8f0686f753ca.

Debian Installation :: 8.3 And Windows 10 Dual Boot GRUB EFI Removed

Feb 3, 2016

I've been using Debian for a few years but always on dedicated boxes and/or VMs.

Finally decided to dual boot Debian and Windows on my main Desktop PC.

Installed as I normally would using, however this time using a seperate drive (one for the existing Windows 10 install and the other for Debian), Debian install detects that windows has an EFI partition and sticks an entry in there, which is fair enough, and everything working fine. Then I spent some time configuring all my software and set it all up just the way I like it. I've rebooted Debian a few times to check it's working correctly and it is.

The issue arrives when I reboot and load into Windows 10. It boots fine.

However after a further reboot GRUB no longer loads... and the machine just boots directly into Windows 10.

After doing some further digging into my EFI partition (and reinstalling various times) it would appear that after a reboot Windows 10 deletes the entry GRUB creates in my EFI partition after EVERY reboot.

Done some googling and most people advise turning off 'fast boot' in Windows as it locks certain partitions to facilitate the machine going into hibernation, only to find that it's always been turned off on my machine (I recall due to a driver issue with my graphics card this had to be turned off when I installed Windows 10).

I've found this article on the Ubuntu forums : [URL] .... however I've tried their steps and windows is still doing a hostile takeover of my EFI partion after a reboot!

Any way to stop Windows 10 from interfering with my EFI files after a reboot? (without doing the obvious thing and kill Windows off).

Debian Installation :: Dual Boot UEFI - Grub Not Recognizing Drive

Mar 24, 2015

I've set up a dual boot system with Debian and Windows 8, both installed on their own drive, with their own boot partition. I installed eveything in UEFI-Mode with fast- and secure boot turned off. Both installations are working, as I can access them by changing the boot priority in the Bios. What I cannot achieve is to let grub boot my windows installation.

This is the output of parted -l:

Code: Select allModel: ATA Samsung SSD 840 (scsi)
Disk /dev/sda: 128GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End    Size    File system     Name  Flags
 1      1049kB  512MB  511MB   fat32                 boot
 2      512MB   111GB  111GB   ext4
 3      111GB   128GB  17,0GB  linux-swap(v1)

[Code] .... 

As you can see, my linux install is on sda, my windows install on sdc (sdb beeing a data disk). This is the entry I made in the 40_custom file in etc/grub.d:

Code: Select allmenuentry "Windows 8.1" {
insmod part_gpt
insmod chain
set root='(hd2,gpt2)'
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
boot
}

I think this should be fine, but if I choose the windows entry wehen grub is booting, it says: error: no such partition. It's my first debian installation, and I am stuck here. Not too much of Linux experience in general.

Debian Installation :: Recover Grub On A Dual Boot Machine With Encrypted LVM

Oct 16, 2015

My laptop setup is:

sda1: W7
sda2: FAT16
sda3: /boot
sda4: encrypted LVM with debian (everything besides /boot)

now I've re-installed W7 so grub was overwritten. I've tried the procedure which worked for me previously:booting with the netinst usb in rescue mode, choosing a root partition to mount, using grub-install to reinstall the grub:

Code: Select allmount /dev/sda3 /boot
grub-install /dev/sda

Now I'm on Jessie (stable), and this time this fails, and I am able to mount only sda3.grub-install doesn't exit so I'm assuming it has been replaced by `grub-installer'. also '/boot' doesnt exist so I created it manually.

Code: Select allmount /dev/sda3 /boot
grub-installer /dev/sda

The latter fails with
Code: Select all/dev/sda/proc not a directory

Debian Installation :: Squeeze- Grub Can't Dual Boot -ntoskrnl.exe Error

Jun 7, 2010

I cannot count how many times I have re-installed squeeze, and do all kinds of fixes to grub, but no joy. Every time, there is this ntoskrnl.exe error, and to re-install it. I thought my WIN XP may be corrupted, so I reinstalled it, and updated it with sp3 and all updates. Then I re-installed squeeze (reformatting all partitions). At the end, the installer ask if I want to install grub to mbr. I replied yes. After reboot, only the 2.6.32.3-amd64 and the recovery kernels show up on the grub screen, no winxp.OK, I booted into squeeze kernel and looked at the /boot/grub/grub.cfg file, and there winxp is not included in /etc/grub.d/30_os-prober section. In terminal, I typed

#os-propber and it found winxp in /dev/sda1
then I typed
#update-grub

and now /etc/grub.d/30_os-prober now show winxp.I rebooted, and winxp shows on the grub screen, and I chose winxp.It came back with "ntoskrnl.exe ...error... re-install ntoskrnl..."Here are the details:

fdisk -l

Ubuntu Installation :: Triple Boot With Current Grub 2 Bootloader

Jul 31, 2010

I currently dual-boot XP and Debian sid. I currently have XP on /dev/sda1, sid on /dev/sda2 with /home mounted separately on /dev/sa3, swap is /dev/sda4. I have free space in both sa3 and 4, mostly in 4, of course. What I'd like to do is add a third partition, either with or without a separate home mount, but have my current grub2 still be the bootloader. I'm thinking I'll give a total of 33 G to it (I keep almost nothing on my hard drive, it's all on the cloud). I want to install Kubuntu and try it out, I've burnt the Live CD and it's very cool.

Debian Installation :: Broken Grub Bootloader After Install On USB Flash Drive

Nov 11, 2015

I have an issue after the installation of debian 8.2 on an usb flash drive:

I had debian 8.2 and windows 8.1 running on a single SSD. Everything was fine. I wanted to install a second debian on a 32gb USB flash drive as a live system. After the installation I am not able to boot my debian (SSD) without the flash drive plugged in. I only get a grub rescue prompt. Booting windows still works. It is also possible to boot both debian systems if the USB drive is plugged in.

So it seems to me, that the debian bootloader was accidently installed to the USB flash drive and the original bootloader on the SSD does not work properly anymore. I used a netinst image from a second USB flash drive to install debian to the first USB flash drive.

Update fdisk output:

/dev/sda1 2048 2050047 2048000 1000M Windows recovery environment
/dev/sda2 2050048 2582527 532480 260M EFI System
/dev/sda3 2582528 4630527 2048000 1000M Lenovo boot partition

Software :: Replace Windows Boot Loader On Sda1 With Grub When Installing Fedora?

May 28, 2010

I recently replaced a failed graphics card w/ a GT 240. Next thing I know, Fedora 11 won't boot up properly. I guess it was a driver issue. I can tell you I went about fixing it all wrong because I wiped the FC11 partition (intending to install FC13) and now I can't boot anything up. My system consists of: sda1 vista, sdb1 XP, sdb5 extended, sdb6 Fedora. I thought grub was on the fedora partition, but reinstalling fedora with grub on that partition didn't fix the boot up problem. Do I need to replace the windows boot loader on sda1 with grub when installing fedora?

My configuration is as follows:

windows is loaded on /dev/sda1. fdisk -l lists this partition as bootable.
linux / is loaded on /dev/sdb1

/home is loaded on /dev/sdb9

Debian :: Grub Boot Loader On A Dual Boot System?

Dec 16, 2010

This is the third time I try unsuccessfully to install Debian as a second OS on a hard drive. When it gets to the end of the installation process the installer asks whether I want to go ahead with the Grub Boot Loader, I choose yes. The end result is however that I can't boot that partition within the hard drive -- i.e., Debian. Can someone tell me what is going on? Should I not use the Grub Boot Loader when I have more than one operating system on a machine? Should I not install Grub on the Master Boot Record (MBR)?

General :: Grub Boot Loader Installation In Dual Boot Machine After Windows 7 Installation?

Mar 23, 2010

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

Just a black screen with blinking underscore to the top left corner. I never had this problem with 9.10, so I am confused. I tried looking around and nothing helped. Be noted that I am an amateur with Ubuntu coding and installing. I did hear that this is already a common issue now.

Fedora Installation :: Dual Boot With Xp - Grub Can't Boot Into Windows?

Jan 10, 2010

I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).

I installed grub on the Fedora disk so as to not touch the windows disk at all.

Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)

My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?

Debian :: Grub Corrupt After Dual Boot Install

Mar 22, 2015

Im currently not an linux expert so I turn to this forum after several attempts to fix my issue with grub.

I had a dualboot single HD with both win7 and win8.1 when I decided to install debian wheezy from usb.

I deleted the win7 partition and installed debian there. The partition scheme is separate /home

After reboot I automatically get into the "Grub rescue mode" and now I´m stuck.

I tried the commands:

set prefix=(hd0,msdosX)/boot/grub/
Insmod normal

I have msdos1, msdos3, msdos5 and msdos6 but nothing is listing anything from the grub rescue mode.

I get the "UNKNOWN FILE SYSTEM" error and cant get past that.

I also tried booting into rescue mode from usb iso install but nothing happens when choosing to repair GRUB.

The listed devices in rescue mode are:

/dev/sda1
/dev/sda2
/dev/sda3
/dev/sda5
/dev/sda6
debian uses sdb 1-2 and sdb1 is the only option to Reinstall GRUB on but it gives me "Unable to install GRUB in /dev/sdb1 This is a fatal error" message
/dev/sdb1
/dev/sdb2
